Possible solution for lost person detection announcements in alexa

[Customer]

Might have overwhelmed the sensor. Meanwhile I came across this older, related thread in a search:

Alexa Person detection announcements stopped working 2

Alexa Person detection announcements stopped working, I tried restarting all 3 echo’s that I have. Cameras still sending iphone text messages. Any Ideas? Thanks for any help. John G

So frustrating. I want to mount my V3s before it gets even colder.
